Find the area of a regular decagon with a perimeter of 60 ft.
Naddik [55]

Answer:

Area of a regular decagon with a perimeter of 60 ft. = 277 squared ft

Step-by-step explanation:

Decagon has 10 sides    So 60/10 = 6 (each side = 6ft )

The sum of the  interior angles of a decagon  is 1 440 degrees.

There are  10 equal isosceles triangles of base angles 72 degrees  in a decagon

Each isosceles triangle can subdivided into 2 right-angled triangles with height h and base length = (6/2) = 3 cm and base angle 72 degrees.

Height of right-angled triangle h = 3 tan 72 ft.

Area of 1 right-angled triangle = (1/2)(3)(3 tan 72) = 13.85 squared ft  

Area of decagon = 20 right-angled triangles = 277 squared ft

Find the equation of the exponential function represented by the table below:
marshall27 [118]

Answer:

y=0.2(0.5)^x is the answer.

Step-by-step explanation:

Let the equation of the exponential function is,

y=a(b)^x

Two points from the given table which lie on the graph are (0, 0.2) and (1, 0.1)

For a point (0, 0.2),

0.2 = a(b)^0

a = 0.2

For another point (1, 0.1),

0.1 = 0.2(b)^1

b = \frac{0.1}{0.2} = 0.5

Therefore, exponential function defined by the given table is,

y=0.2(0.5)^x

Explain how you can use a number line to show that 5/8 is greater than 3/8
Vera_Pavlovna [14]
On a number line, you could divide the eighths evenly and mark where the 5/8 are and where the 3/8 are. Then you will be able to see which one is farther on the number line.

F(x)= 7.45x +33.7 at x=-4.3
weeeeeb [17]

To solve this function, all we need to do is substitute -4.3 in for wherever "x" appears and then simplify.

f(x) = 7.45x + 33.7; x = -4.3

f(-4.3) = 7.45(-4.3) + 33.7

f(-4.3) = -32.035 + 33.7

f(-4.3) = 1.665

This means that, when x = -4.3, f(x) = 1.665.

Note: It may help to remember that, in a function such as this, f(x) can be thought of as the "y" value that corresponds to the given "x" value (in fact, when writing it out with words, f(x) is the same as "function of x"). And, if you are given a value for f(x), then the opposite is true. Just substitute in the value given for f(x) and solve for x.

Hope this helps!
